Each test contains multiple test cases. The first line contains the number of test cases t𝑡 (1≤t≤1001≤𝑡≤100). The description of the test cases follows.The first line of each test case contains only one positive integer n𝑛 (1≤n≤1001≤𝑛≤100), representing the number of problems.The second line of each test case contains an array a𝑎 of length n𝑛 (1≤a1≤a2≤⋯≤an≤1091≤𝑎1≤𝑎2≤⋯≤𝑎𝑛≤109).The third line of each test case contains an array b𝑏 of length n𝑛 (1≤b1≤b2≤⋯≤bn≤1091≤𝑏1≤𝑏2≤⋯≤𝑏𝑛≤109).OutputFor each test case, print an integer as your answer in a new line.ExampleinputCopy261000 1400 2000 2000 2200 2700800 1200 1500 1800 2200 300064 5 6 7 8 91 2 3 4 5 6outputCopy23

Given an integer t, the number of test cases for each test case ,Given an integer n, print True if it is a power of two. Otherwise, print False.An integer n is a power of two, if there exists an integer p such that n == 2ᵖ.Input FormatInput from stdin will be processed as follows and passed to the function.The first line contains an integer t, the number of testcases.The next n lines contain each test caseConstraints0 <= t <= 5000 <= n <= 1000Output FormatThe output is Either a print statement of True or FalseSample Input 012Sample Output 0True

The input begins with the number t of test cases in a single line (t<=10). In each of the next t lines there are two numbers m and n (1 <= m <= n <= 1000000000, n-m<=100000) separated by a space.OutputFor every test case print all prime numbers p such that m <= p <= n, one number per line, test cases separated by an empty line.ExampleInput:21 103 5Output:235735

You are given an array 𝐴A of size 𝑁N.Find the largest integer 𝐾K such that there exists a subsequence 𝑆S of length 𝐾K where 𝐾K is divisible by the number of distinct elements in 𝑆S.Input FormatThe first line contains a single integer 𝑇T, denoting the number of test cases.The first line of each test case contains a positive integer 𝑁N, the length of array 𝐴A.The second line contains 𝑁N space-separated integers, 𝐴1,𝐴2,…,𝐴𝑁A 1​ ,A 2​ ,…,A N​ −− denoting the array 𝐴A.Output FormatFor each test case, output the largest valid 𝐾K.Constraints1≤𝑇≤1041≤T≤10 4 1≤𝐴𝑖≤𝑁≤2⋅1051≤A i​ ≤N≤2⋅10 5 The sum of 𝑁N over all test cases won't exceed 2⋅1052⋅10 5 .Sample 1:

You are given an array 𝐴A of length 𝑁N, and an integer 𝐾K.You can perform the following operation:Choose any index 𝑖i (1≤𝑖≤𝑁1≤i≤N), and increase 𝐴𝑖A i​ by 𝐾K.Find the minimum possible value of max⁡(𝐴)−min⁡(𝐴)max(A)−min(A) attainable, if you can perform this operation as many times as you like (possibly, zero times).Input FormatThe first line of input will contain a single integer 𝑇T, denoting the number of test cases.Each test case consists of two lines of input.The first line of each test case contains two space-separated integers 𝑁N and 𝐾K — the length of the array and the parameter 𝐾K.The second line contains 𝑁N space-separated integers 𝐴1,𝐴2,…,𝐴𝑁A 1​ ,A 2​ ,…,A N​ — the initial values of the array elements.Output FormatFor each test case, output on a new line the answer: the minimum possible value of max⁡(𝐴)−min⁡(𝐴)max(A)−min(A) if you can perform the given operation any number of times.Constraints1≤𝑇≤1051≤T≤10 5 1≤𝑁≤2⋅1051≤N≤2⋅10 5 1≤𝐾≤1091≤K≤10 9 1≤𝐴𝑖≤1091≤A i​ ≤10 9 The sum of 𝑁N over all test cases won't exceed 2⋅1052⋅10 5 .Sample 1:InputOutput43 41 5 43 212 8 44 11 43 62 8256 121 2 4 128 130 1311008Explanation:Test case 11: Increase the first element by 𝐾=4K=4 to obtain the array [5,5,4][5,5,4].Here, max⁡−min⁡=5−4=1max−min=5−4=1, which is the best possible.Test case 22: The second and third elements can be increased by 22 till they reach 1212, at which point all the elements of the array are equal, so max⁡(𝐴)−min⁡(𝐴)=0max(A)−min(A)=0.Test case 33: Since 𝐾=1K=1, again it's possible to make all the elements equal.Test case 44: Do the following:Increase 𝐴1A 1​ by 1212 repeatedly to make it 133133.Increase 𝐴2A 2​ by 1212 repeatedly to make it 134134.Increase 𝐴3A 3​ by 1212 repeatedly to make it 136136.The array is now [133,134,136,128,130,131][133,134,136,128,130,131].For this array, max⁡(𝐴)−min⁡(𝐴)=136−128=8max(A)−min(A)=136−128=8.It can be shown that this is optimal.

The first line contains a single integer n (1 ≤ n ≤ 150) — the number of statements in the programme.Next n lines contain a statement each. Each statement contains exactly one operation (++ or --) and exactly one variable x (denoted as letter «X»). Thus, there are no empty statements. The operation and the variable can be written in any order.OutputPrint a single integer — the final value of x.ExamplesinputCopy1++XoutputCopy1inputCopy2X++--XoutputCopy0
